Definitions

  • the present invention relates to a roller skate in which the footwear is fastened to the roller-carrying carriage by means of locking means which enable the position of the footwear and the carriage relative to one another to be altered.
  • the present invention can be extended, without changing its innovative concept, for example, to bladed skates for use on ice, and in general to footwear having a rigid sole, such as, for example, a ski boot, and having an item of sporting equipment applied to its sole.
  • the adjustment of the position of the footwear and the roller-carrying carriage or frame relative to one another is one of the basic aspects to which the user attaches particular importance and it is also known to both the manufacturer of that article and to the user that the above-mentioned adjustment is a function which depends directly on various parameters, such as, for example, the greater or lesser experience of the skater and the specific requirements which arise from time to time as a function of the type of route or terrain on which the skates are used.
  • Typical examples of the choices made by the user are the arrangement of the rollers aligned in parallel or disposed along the median longitudinal plane of the footwear or along planes inclined relative to the above-mentioned plane. In other cases, a footwear position which is advanced or moved back relative to the carriage or frame is required.
  • Roller skates having locking means that enable the position of the footwear and the roller-carrying carriage relative to one another to be altered are known in various forms because the above-mentioned feature is all-important in guiding users as to their choice of one type of skate rather than another.
  • the main aim of the present invention is to provide a structure of a roller skate, especially an in-line roller skate, which does not have the disadvantages mentioned briefly above.
  • a more specific aim of the present invention is to provide a roller skate of which the novel configuration and form enable the above-mentioned adjustment to be effected extremely rapidly and in a well defined manner whatever the position desired by the user.
  • An even more precise aim of the present invention is to provide a roller skate with which only one operation is required for the appropriate positioning of the footwear relative to the frame because, for each adjustment, the necessity for subsequent adjustment, as is necessary in conventional skates, is excluded.
  • roller skate as described in detail hereinafter, of the type comprising a carriage or frame on which a series of running rollers is mounted in a freely rotatable manner and which is provided with means of fastening to the rigid sole of an item of footwear which are temporarily releasable in order to alter the position of the footwear and the carriage relative to one another.
  • the fastening means are arranged on a pair of substantially stationary cross-members with which the carriage is provided, and the invention is characterised in that an element for connecting the carriage to the sole of the footwear is associated with each of the cross-members and is connected to the sole eccentrically, the position of the connecting element in the released state being alterable in order to permit movement for adjusting the position of the footwear and the carriage relative to one another, and the connecting element being lockable on the cross-member in order to fasten the footwear and the carriage relative to one another when the desired position has been reached.
  • FIGS. 1 to 8 are diagrammatic plan views of the roller-carrying frame in a first embodiment which show, as explained hereinafter, some of the various possible adjustments of the position of the footwear and the carriage relative to one another;
  • FIG. 9 is an exploded diagrammatic perspective view of the front end of the skate according to the present invention in the first embodiment
  • FIG. 10 is a view analogous to FIG. 9 of only the front end of the roller-carrying carriage
  • FIG. 11 is a perspective view of only the cam means connecting the carriage to the footwear, still in accordance with the first embodiment
  • FIG. 12 is a plan view of the front end of the roller-carrying carriage in the first embodiment
  • FIG. 13 is a view of the front end of the skate on section B--B of FIG. 12;
  • FIG. 14 is a view of the front end of the skate on section A--A of FIG. 12,
  • FIG. 15 is an exploded diagrammatic perspective view of the front end of a variant of the skate according to the present invention.
  • FIG. 16 is a view analogous to FIG. 15 of only the front end of the roller-carrying carriage in said variant;
  • FIGS. 17 to 25 are diagrammatic plan views of the variant of the roller-carrying frame which show, as will be explained hereinafter, some of the various possible adjustments of the position of the footwear and the carriage relative to one another.
  • 10 generally indicates the skate carriage or frame on which the running rollers, which are not represented because they are not necessary in order to understand the present invention, are mounted in a freely rotatable manner.
  • the frame or carriage 10 comprises, in known manner, a body 12 which is substantially in the form of an inverted U and which therefore has two side limbs 14 and 16 (the two sides of the U) provided with aligned and opposing holes 18 which are used for mounting the hubs (not shown) for the rotation of the running rollers R, two of which are shown partially only in FIG. 14 for sake of clarity.
  • FIGS. 1 to 8 the shape of the footwear generally indicated 20 is shown schematically and with a broken line.
  • the carriage 10 has, substantially in the vicinity of its ends, two stationary cross-members 22 and 24 which accommodate means for connection to the footwear 20 which, as will be explained hereinafter, are means which fasten the carriage 10 and the footwear 20 relative to one another and which can be temporarily released in order to adjust the mutual positions thereof.
  • FIGS. 1 to 8 a list will now be given hereinafter, Figure by Figure, of the various possible adjustments, the direction of movement of the footwear 20 always being indicated by the arrows, all of which are marked with the letter F and are not differentiated from one another by a reference numeral because their meaning is clear from the representation.
  • FIG. 1 illustrates a movement of the shoe 20 in the direction towards the front end of the skate 10
  • FIG. 2 is an analogous drawing illustrating a movement in the opposite direction, that is to say, towards the rear;
  • FIG. 3 illustrates a side or transverse movement towards the right
  • FIG. 4 represents a movement in the opposite direction, that is to say, towards the left;
  • FIG. 5 represents a clockwise or anticlockwise rotation of the front end of the shoe 20 relative to the carriage 10;
  • FIG. 6 is a view representing an analogous movement of the rear end of the shoe
  • FIG. 7 illustrates a clockwise rotation of the shoe 20 relative to the skate 10
  • FIG. 8 is a view analogous to FIG. 7 representing a rotation in the opposite sense, that is to say, an anticlockwise rotation.
  • carriage 10 is provided, in each of the substantially stationary cross-members 22, 24, with an element for connecting those cross-members 22, 24 to the rigid sole of the footwear 20, the front end of which, shown in particular in FIGS. 9 and 14, is generally indicated as 26.
  • FIGS. 9 to 14 A description will now be given hereinafter of the releasable locking means by means of which the footwear 20 is fastened to the carriage 10, referring especially to FIGS. 9 to 14 but naturally bearing in mind also FIGS. 1 to 8.
  • the detailed description of those fastening means will be given with reference to the front stationary cross-member 22 but it will be appreciated that the analogous means for connecting the cross-member 24 to the sole of the footwear 20 are substantially identical and therefore their representation and description are superfluous.
  • the cross-member 22 has, on its lower face, that is to say, that facing the inside of the carriage 10, a substantially cylindrical and internally hollow projection generally indicated 28 which delimits, with the lower face of the cross-member 22, a substantially cylindrical seat 30, the inside of which accommodates a discoidal element 32 which has a substantially circular contour and which, according to one of the main features of the present invention, is connected eccentrically to the sole 26 of the footwear 20.
  • the discoidal element 32 has, at the bottom, a central pin 34 which is inserted in a freely rotatable manner in a suitable seat of a screw or dowel 36 screwed onto the lower face of the projection 28.
  • the discoidal element 32 is connected eccentrically, as explained hereinafter, to the sole 26 of the footwear 20.
  • connection in the embodiment shown in more detail in FIGS. 9 to 14, comprises a pin 38 having a non-threaded portion 41 which is introduced into an opening 40 in the cross-member 22 until its threaded end 39 is screwed into a corresponding hole in the discoidal element 32.
  • connection between the pin 38 and the discoidal element 32 is of a substantially eccentric type and, as will be explained hereinafter, the connection permits all of the movements shown by way of example in FIGS. 1 to 8 and also the intermediate movements not specifically represented, as will be explained hereinafter.
  • the pin 38 is applied to the cross-member 22 of the carriage 10 of the skate, in particular to the discoidal element 32, by passing through the opening 40 in the cross-member 22, by means of the interposition of a washer 42 which has a central hole 43 for the passage of the pin 38 and which is accommodated in a suitably shaped seat 44 in the sole 26 of the footwear 20.
  • a washer 42 which has a central hole 43 for the passage of the pin 38 and which is accommodated in a suitably shaped seat 44 in the sole 26 of the footwear 20.
  • that embodiment is not to be regarded as limiting the invention because the application of the pin 38 to the discoidal element 32 in order to lock it and release it can be effected in another, equivalent manner.
  • the rear end or at least the rear portion of the sole of the footwear 20 is connected in an entirely analogous manner to the rear cross-member 24 in which, in FIGS. 1 to 8, the same elements are indicated with the same reference numerals.
  • 46 indicates a suitably shaped slot extending from the wall 14 of the carriage 10 as far as the region of the seat 30 accommodating the discoidal element 32.
  • the slot 46 is provided purely to enable the discoidal element 32 to be introduced as far as the above-mentioned seat 30. It will be appreciated that the introduction opening of the slot 46 could be closed, at any rate for reasons of a purely aesthetic nature, by the application of an insert or the like (not shown) which is introduced into the slot 46 to mask it and, at the same time, to permit rotation of the discoidal element 32, when required, in order to adjust the position of the sole 26 and the carriage 10 relative to one another.
  • the starting point will be assumed to be the state of FIG. 1 which illustrates the footwear 20 in its position of maximum advance towards the front end of the skate and which state is clarified by referring to FIG. 14, and it will be assumed that the locking and positioning means associated with the rear cross-member 24 are in states equivalent to those of the corresponding means associated with the cross-member 22.
  • the arrows F of FIG. 1 indicate that that state or position can be achieved by moving the footwear 20 forwards relative to a different position, for example, one of those illustrated in FIGS. 2 to 8.
  • the movement composed substantially of rotation and translation of the footwear 20 takes place and is assisted by the simultaneous rotation of the discoidal element 32 inside the seat 40 of the cross-member 22, 24, while the threaded pin 38, which is rotatable and moveable only axially relative to the sole 26, remains raised and rotates inside the hole 45 of the sole 26.
  • the skate according to the present invention can, while maintaining its innovative concept unaltered and substantially the same, be produced in a variant described briefly hereinafter with reference to FIGS. 15 to 25. Purely for the sake of simplicity and brevity, the same component elements provided in the above-mentioned variant and corresponding to those of the first embodiment are indicated by the same reference numerals.
  • both of the discoidal elements associated with the stationary cross-members 22 and 24, and which are now marked by the reference 32A, are substantially polygonal and, in the non-limiting embodiment represented, they are more precisely octagonal, but it will be appreciated that a discoidal element 32A having a greater or lesser number of sides could achieve the same aim satisfactorily.
  • the seats accommodating the discoidal elements 32A which seats are now marked with the reference 30A, have a shape corresponding substantially to half of the contour of the discoidal element 32A so that the latter engages with the seat 30A with three of its consecutive sides while the two sides adjacent to the previous sides engage slidably with the walls of the slot 46 which, as stated above, enables the discoidal body 32A to be introduced as far as the seat 30A.
  • FIG. 17 illustrates a movement of the shoe in the direction towards the front end of the skate parallel with the median longitudinal axis of the carriage
  • FIG. 18 is a Figure analogous to the previous Figure illustrating a movement in the opposite direction, that is to say, backwards towards the rear end;
  • FIG. 19 illustrates a clockwise rotation of the front end of the footwear relative to the front end
  • FIG. 20 illustrates a rotation opposite to that of the previous Figure
  • FIG. 21 illustrates a rotation of the footwear analogous to that of FIG. 19 with the footwear in an advanced position
  • FIG. 22 illustrates a rotation that is symmetrical and opposite to that of FIG. 21;
  • FIG. 23 illustrates a rearward movement of the footwear in a plane parallel with the longitudinal plane of the carriage
  • FIG. 24 illustrates a side movement parallel with the median longitudinal plane of the carriage
  • FIG. 25 illustrates a symmetrical movement of the footwear relative to that of FIG. 24.
  • skate according to the present invention can be extended to any type of shoe with a rigid sole to the bottom of which an item of sporting equipment, such as, for example, as mentioned above, a bladed skate for ice-skating or a ski boot is fastened.
